i Be. it known" that I, EnwARo Wl GoonwiN,

' ,a. citizen of the United States, and a resident ofthe borough of-Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Drop-Door-Gperating Mechanism for Dumpingflars, of which the following is a specification, accompanied by drawings. This invention relates to mechanism for operating the valves or drop doors of railway dumping cars or vother dumping vehicles, and one of the objects of the inventionis to enable the compartments of a call to be discharged either separately .or simultaneously bymeans which insure-the safety of t-heoperators at all times andare easily and quickly manipulated with. the least amount of effort. Another object of able the drop doors for each compartment to be separately returned to closed position,

without interference from the mechanism for simultaneously opening the doors.

Further objects of the invention will hereinafter appear, and to these ends the invention consists of apparatus for carrying out all of the above objects, embodying the companying features of construction, combinations of elements, and arrangemelltof parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the acdrawings. in which- Figure 1 is a side elevation, partly broken away, of a railway dumping car embodying the invention; Fig. 2 is a top plan view of one end of the car partly broken away; Fig.

3 is a transverse sectional view on the line 3.-3 of Fig. 1; Fig. 4 is an enlarged detail view partly in transverse section of the mechanism for operating the drop doors as shown at the left of Fig. 3; and Fig. 5 is a side'elevation of Fig. 4, looking in the direction of the arrow, and partly in longitudinal section, showing the end of the caron the line 5--5 of Fig. 2.

Referringto the drawings, A represents 1 the body of a railway dumping car having.

compartments formed by the transverse bulkheads B, and each compartment is pro rided with the centrally hinged drop doors f jspeciflcation of glitters Patent. Application filet1 "Iune 2a, 1910;- smm 1%. 568,429.

the invention is to en-' .PatentedMay .G. The car trucks maybe of'any suitable" construction' comprising the 'wheels D and connecting parts supporting the truck bolsters E'upon which are supported the body bolsters F by means of the socket 'bearin G, and bearing plates H secured to the b0 y bolsters. The center sill J may beformed of I-beams supported upon the body bolsters.

F and extending throughout the length of.

the car, upon which are carried the built up" needle beams K forming yokes-forsupport ing the drop doors C when :opened. The

drop doors C are pivoted at L to the needle beams by any suitable form of non-leaking hinge. The transverse bulk heads B over the trucks preferably-extend downwardly below the drop doors C, to the ends of'the- .70 the center sills andbracedas by means of body bolsters 'F and are suitably secured to the braces O. The intermediate and end bulk heads B preferably extend to the bottom of the center sill J.

In. a hopper bottom railway dumping'car' of the type shown, for il-lustr a iting the in-- vention, the sides of the compartments are provided with aprons P-extending down-- wardly and inwardly to protect the mechanism for operating the drop doors C. Theoperating mechanism is located within the spaces between the sides of the car andthe aprons and comprises-in this instance suitable ratchet detent mechanismsfor operating the chain shafts Q, up'on ,'which are 1 wound and unwoundthechains R connect-v ing to the outer ends of the drop doors C.

The ratchet detent mechanisms are preferably controlled by power. multiplying de-' vices which release the ratchet wheel Sand.

hold the detent arms T to permit the "drop doors" to open under load, without interference from the detent s, tl1us. preventing the detents from accidentally engaging the ratchet wheels while the compartment is dis charging and thereby insuring the'safety of the operators at all times. The power Hilll tiplying-devices for controlling the ratchet detent mechanisms are .preferably' in the form of toggle acting levers. although any suitable form of power multiplying devices may be used. Means are provided for sepas. rately operating the pairs of doors Gv of feach compartment of the car and suitable inechanism is connected with said discharg 1 ing'means for simultaneously discharging the compartments. ,Means are also provided 'forT'eturning "the doors of each compartment-separately' to closed position without interference from'the mechanism for simultaneously opening-the doors.

The "drop. doors C may be of ,anysuitable construction," are. shown provided at. the. ends with the 2 bars Uiconnecting the sides lZ'f-ofthe doors and fanning lips W, under whichcreeping shafts a may be moved to lock the-doorsin closed position.

;-.1;. Th e chain shafts Qare supported in suitable hearings) which may be secured to the :1nner-sides of the'car body and theratchet wheels S-are provided with shroud flanges g'l'yingat each: side of the ratchet T. The detent bars T. are-provided with the detents it cooperating with the teeth i and these 39 bars' are preferably. curved and provided with lugs j adaptedto bear upon the shroud Thebars T mayflange's'g of the ratchets.- alsdibe weighted at 70; The detent bar T is pivoted-at 0' to the short link 39 which is in .3 turn; pivoted at g to the bracket r suitably secured to the apron P. The normal position of the pivot 0 when the ratchet is in .locked position is somewhat inboard of the axis of the studs jso thatthe detent tooth h is urged by gravity into engagement with the ratchet wheel S. Furthermore, the lmuckle 'of the toggle formed by the arm T and link 1) is ,normally slightly beyond the dead center line, so that the tendency of the parts is to be maintained in locked position under pressure from the ratchet wheel S under load.

Pivoted at 0 is the link 8, the outer endof which is pivotally connected to the lever arm t extending inwardly from the hub 24 pivoted at 41 on the bracket w secured to the side of the car body. This hub u is provided with the removable operating handle which may be operated by reaching .55ithrough the opening 3 at the side of the car.

' The operating handle m is shown in this in stance provided with a clutch member 2 adapted to cooperate wit-h the clutch mem ber 3 on the hub a. By pulling the lever downwardly and outwardly the pivotal connection between the lever arm 2? and link 8 is raised, thereby breaking the toggle and moving the pivotal connection between the detent arm T and the link 79 upwar'dly thus lifting the detent tooth 72 out of engagement ed at 11 to the screw threaded withthe teeth of the "ratchet Sandpermitting the drop doors to;yopen under gravity. The lugs jat the lower. end 'of the. detent armT travel on the shroud flanges g and the detent tooth Jzis quickly disengaged from vthe teeth of the ratchet wheel and maintained out ofj'ie'ngagement .as longas desired withoutdanger of kicking back. The ends at of the 'hain shafts-Q as shown. extend opposite-the openings'b in the sides 5 of. the car and 'ar'eadapted to receive aratchetf'wrench 6 for rewinding the chains and closing the drop doors C. The mechanism for simultaneously opening the doors of the diiferent compartments of the-car is connected to the power mult-iplying devices controlling the ratchetdetent mechanisms and in'opera'ting the doors si- 'multaneously, the hand levers as should be preferably disconnected from the 'power- 35 multiplying devices at the clutch members 2 and 3, sothat these handles will not be projected outwardly beyond the carbody. As shown in this instance, bars or rods 7 extend longitudinally of the car adjacent the operating'devicesfor the drop doors beneath the aprons P. Screw threaded ends 8 projecting beyond the end of the car are connected to the :rods 7 by means of short links 9 pivoted at 10 to the rods 7 and pivot- 5 ends 8, so that slight vertical play of the rods 7 is afforded. The screw threaded ends 8extend through the bearings 12 and. are :provided with the nuts 13 having arms 14:, and each 10o screw threaded end 8 is provided with a hand wheel 15 or other hand device loose upon the shaft and adapted to be connected "to the arm 14:, as by means of the pin 16. By turning the wheell5 and nut 13 the rods 7 will be moved longitudinally of the car. Pivoted on shafts 17 supported by brackets 18 and 19 are bell crank levers 20, the longer arms 21 of which are provided with pins 22 engaging longitudinal slots 23 in the rods 7. The shorter arms 24 of the bell crank levers 20 are pivotally connected by links 25 to the links 8 of the power multiplying devices.

In normal position the pins 22 lie at the inner ends of the slots 23 in the bars 7, so that by moving said bars longitudinally in a direction to rock the bell crank levers 20, the pivotal connection between the links 5- and t will be raised and the detent teeth h of the detent bars T simultaneously withdrawn from the ratchet wheels S. By this means all of the pairs of drop doors C maybe simultaneously operated. y

In rewinding the chains upon the chain. shafts Q the detent teeth 71 travel over the teeth of the ratchet wheels and movement ofthe toggle acting devices is permitted by reason of the lost motion connection between the bell crank levers 20 and the longitudinal bars 7.
